Why is it so windy ?

Asked by: 3916 views , ,
General Aviation, Student Pilot

Before going to fly yesterday, as usual I checked all I can find on weather (Metar, TAF, weather depiction chart, wind aloft....).  They all agreed that it was going to be mostly a good day to fly. The wind aloft was reporting some strong wind. I went flying and as it said....wind showed up in the afternoon with some gust to the 20/25 knots. It was a bumpy ride. As soon as I came back home, I took a screenshot of the Surface Analysis Chart (http://pasteboard.co/158EGW9o.png) . I thought that it was possible to predict the strength of the wind by how close the isobars are on the chart. So what am I missing there. How come the isobars do not seem to show a strong wind then.

ps: I was flying in the East Tennessee Region (marked by the red circle). 

Also, another stupid question. I thought that a cold front (or a warm front) usually means bad weather. So home the day was a good day to flight with the cold front above our head that day !

    Well if you look closer at the chart. You are flying right at the boundary between the high pressure system to the west and the low pressure system to the NorthEast and the isobars are really not that far away. Also and most important a cold front just went through and a cold front will always leave residual winds.
